Although Dell offer a few computers with Ubuntu pre-installed they actively discourage you from buying them.

For example this page 'Windows or Ubuntu?' (http://www1.euro.dell.com/content/topics/segtopic.aspx/windows_or_ubuntu?c=uk& cs=ukdhs1&l=en&s=dhs) says:

Choose WINDOWS if:

* You are already using WINDOWS programs (e.g. Microsoft Office, ITunes etc) and want to continue using them
* You are familiar with WINDOWS and do not want to learn new programs for email, word processing etc
* You are new to using computers

Choose UBUNTU if:

* You do not plan to use Microsoft WINDOWS
* You want to learn new programs for email, word processing etc
* You are interested in open source programming

No mention of ease-of-use, no mention that Ubuntu and its applications are FREE, no mention of security etc.

PAE kernel should be installed by default after detecting the RAM with Ubuntu.

With the new LTS coming in April I would like to see Ubuntu promote the idea for this release for a long period.

I have a lot of friends who are still on Hardy Heron and do not wish to upgrade every 6 months. They have everything working the way they want and are afraid they will have to search for buttons which are no longer on the place they're used too. They also do not need bleeding-edge software.

(When people buy a Windows PC they leave Windows on it until they buy a new computer. They do not upgrade to the newest version.)

Ubuntu Installs lots of Applications that are useless for many users or machines.

Example: Bluetooth Manager. Many laptops and mobile devices have bluetooth capabilities, but many others don't. So it's basically useless for those people with no Bluetooth capability. Why activate such service in uncapable hardware? Wouldn't it be cool that all those packages were removed easily?

I have to change Evince setting when reading different document types. For example:

If I'm reading a paper, I'd like "Continuous" scrolling on, and zoom on "Fit Width"

If I'm reading a slide, I'd like "Continuous" off, and the zoom on "Best Fit"

Network Manager in Karmic koala does not work with DSL connection with IP address configuration automatic(DHCP). The network manager in ubuntu 8.10 was the best. Bring it back in Lucid Lynx...

I think it is very difficult to rename a file in nautilus.

At first you have to right click on a file or folder and then choose the function rename.

In many ways its very difficult to approach network mounted drives using an application it self.

by example:

There are alot of applications that just dont see the network bookmarks you have made in nautilus. If you open the application and try to open a file using "file-->Open" and try to search on a network drive you have to do alot of other things to accomplish that. The next step would be first to mount the bookmark. Then use "File-->open-->go to ".gvfs" but you have to enabled the "hidden folders" and then you can approach your file.

There are alot of programs that dont see those bookmarks. Gedit however is one of the programs that does do the right thing. Why this should be worked on is if you want to mount a iso file you cant right click on it and say mount.

I find awkward that currently you have to power up the machine, wait some time while the system loads, authenticate, and then wait some other time while the desktop loads.

It feels more natural to me to have a prompt just after power-up (even if it has to be less eye candier) and, after that, go straight to desktop.

So the idea would be to move the prompt as early in the boot sequence as feasible. Current greeters can of course remain for logouts/user switchs.

Recently i was installing ubuntu for a Georgian. He knows two languages: georgian and russian.
And due to georgian translation incompleteness some names was displayed in english. At the same time this strings was translated in russian. But to see this you have to relogin each time.
